Identifying Ford 351 Cylinder Heads
To identify the cylinder heads on a Ford 351 engine, there are a few methods you can use:
1. Valve Cover Method:
– The quickest way to identify a Ford 351 Windsor engine is to count the number of bolts on the valve covers. The valve covers are located on the top of the engine, one on either side of the air cleaner, and each will have six bolts. If the valve cover is removed, you will see “351” stamped on the cylinder head in the valve valley.
2. Casting Numbers:
– Look for the casting number on the head gasket side near one of the central intake ports. The casting numbers are on the bottom side of the head in between the pushrod holes. You may need to remove the intake manifold and use a mirror to see them. Once you have the casting number, you can look up the specifications online .
3. Cylinder Head Code Stamp:
– The Ford cylinder head code number can be located in three different places: on top of the head under the valve cover, on the bottom of the head (which requires the head to be removed), and on the side of the head just under the valve cover lip. If the valve cover is off, look for any code number at either end of the head.
It’s important to note that the casting numbers and other identifying marks can vary based on the year and model of the engine, so it’s recommended to use a combination of different identification methods to positively identify the cylinder heads.
If you have the casting number, you can look up the specifications online to determine the specific type of cylinder head you have.
